How it works

Feeling anxious or depressed in hyperthyroidism comes from how the brain responds to stress and illness, not from how much thyroid hormone is in the blood. The brain's emotional circuits change on their own, regardless of thyroid hormone levels.

Most probable mechanism

In Simple Terms

Anxiety, depression, and stress result from changes in brain circuits that process emotions and threat, and these changes happen separately from how much thyroid hormone is in the blood. Even when thyroid hormone levels are very high, the brain's emotional response does not automatically become more intense.

Causal chain
1

Neural circuits in the prefrontal cortex, amygdala, and hypothalamic-pituitary-adrenal axis exhibit altered activity patterns in response to chronic psychological stressors, independent of circulating thyroid hormone concentrations.

In adults newly diagnosed with hyperthyroidism, over 40% have moderate to severe anxiety and over 50% have moderate to severe depression; these mental health symptoms often remain even after thyroid hormone levels return to normal.
